No, since all OSEs must implement the integrations following specific rules described in the SUNAT interoperability manual (http://cpe.sunat.gob.pe/node/88) and cannot introduce any modification.

“I noticed my OSE validation differs from SUNAT validation. What should I do?”
If the response differs from the description in SUNAT interoperability manual, contact SUNAT for validation (see below), otherwise clarify with your OSE service provider.
Does SAP recommend any specific OSE?
No, all SUNAT certified OSEs are supported.
SAP does not certify OSEs, SUNAT certify their interoperability.
OSEs have very different commercial rules, typically SAP customers run testing environments after going live. Make sure to clarify all support aspects accordingly.
What validations should I run before going live with my OSE?
UBL 2.1 is very comprehensive in terms of validations. From this perspective documents validations could a be pretty resource intensive task. It is recommended to run stress testing and volume testing well in advance with your OSE.
SAP also recommends to test all your business use cases with your OSE before switching from SUNAT direct connection.
